I have issue with mobile view: on iOS Safari 11.3 (at least on an iPhone SE) the login name overlaps the avatar, which looks really weird... same with the search bar having allocated space but it's not being used.

Here's a screenshot attached, look at the blue arrow. The yellow arrow is meant to signify the other less important issue.

1- Firstly I would like to know how to increase the width of the forum2- If you increase the width of the forum, will the menu have more space for the icons? If not how do I increase the menu too?3- I searched the theme and did not find where I change these icons, I would like to change them, how do I?
